Weather in September
Temperature
The shift into September reveals an average high-temperature of a still hot 33.5°C (92.3°F), closely mirroring August's climate. During September nights, Manéssé witnesses a consistent average temperature of 24.2°C (75.6°F).Heat index
The heat index in September is computed to be a blistering 43°C (109.4°F). Vigilance: Heat cramps and heat exhaustion are likely. The likelihood of heatstroke increases with continued activity.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

The months with the highest UV index are March through June and September, with an average maximum UV index of 8. A UV Index of 8 to 10 symbolizes a very high threat to health from unprotected exposure to Sun's UV rays for the ordinary person.Note: A maximum high UV index of 8 in September translates into the following recommendations:
Immediate precautions are necessary; otherwise, skin and eyes might get damaged quickly. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
